It shouldn't be an issue as the wildcard record will only take effect
for domains for which there is no other record. If there are MX
records for a FQDN then there willbe NS records for that domain and
verisigns wildcard won't get a look in.

Nah verisign are only breaking non-existant domains, and lots of other
things as a side effect, if the domain exists regardless of what other
records it has then the wild card record won'tmake any difference.
